The Arista 7250X Series are purpose built 10/40GbE switches with wire speed layer 2/3/4 performance combined with low latency and advanced features for software driven cloud networking, big data, cloud, virtualized and traditional deployments.

The 7250X Series enables highly scalable two-tier network designs with MLAG, ECMP and VXLAN technologies.

40GbE Spine and Spline™ solution for open, simple and scalable networking

The Arista 7250QX switches deliver wirespeed 40GbE performance, offering the highest density 2RU 10/40GbE switch in the world. The 7250QX-64 is the ideal switch for:

  • Ultra-high density 40GbE switching in a compact fixed form-factor
  • Collapsed Spline for middle or end of row designs replacing legacy switches
  • Purpose-built spine aggregation switching (5.12 Tbps switching capacity)
  • Scaling uplink bandwidth between data center leaf switches
